Dalaran Freeze

Please forgive my ignorance, am very new to this. Have made a private server with a repack and everything is fine until I get to Dalaran. If I ".recall port Dalaran" I go to the crater, if I fly in it freezes upon entry and if I portal as a mage it freezes upon entry. Have tried restarts and all with no luck. Can't log on to toons there as they freeze as soon as it comes up. Toons elsewhere work fine. I have tried the search and couldn't find anything close enough...

TIA

Arcemu right ?

Try compile a core by yourself its better, and you will be able to apply fixes & cool C++ scripts.
Search for a tutorial... there are many! :)

Yeah upgrade your core and database, this should fix the problem!

Is this wotlk or cata?
